Glue gun: what better tool to select

Not so long ago replaced by a different adhesive solutions and mixtures by a new modern tool called Glue Gun: which one is better to choose for a particular purpose, this article will tell. Publication introduces its structure, operating principle, advantages and species. The device can not only safely glue a variety of surfaces, but also quite convenient in use. This is what will be discussed further.

Why the need for glue gun: features and scope

There is such a thing as a folk instrument. To this category belong for a long time to win the love of consumers screwdrivers and drills omnipotent. Recently, this list can be safely attributed and thermobonding gun. It does not require much advertising and propaganda, as it appreciated by the users themselves, and have included the subject in their instrumental arsenal. He is popular among both professional builders and housewives-handy people.

Melt adhesive price relatively low. In addition, it has a simple construction and is very convenient to use. When this is not a necessity in the household. At the same time it can be used to solve a wide variety of tasks, and in some cases, the tool is simply indispensable.

Gun with glue helps so much easier to produce bonding, while its use is not only a few times more efficient, but also much more economical. Bonding takes place with the help of just a matter of seconds, and virtually any surface. Professional glue gun scope is very wide: it is used sellers in shopping sites, warehouse porters, construction workers for repair work, needle and even children, inventing their own little masterpieces hands.

A tool such as thermobonding gun - really a necessary thing in many industries and indispensable tool in almost any home. At the same time there are a number of indisputable factors that affect the correct choice of such a universal tool, because each of its sub-species has its own characteristics and properties. So you need to understand in more detail the purpose for which will use the glue gun.

That glues the glue gun where it is used by professionals and amateurs

As mentioned above, the scope of the glue gun is very wide, it is able to glue the various parts and materials. In particular, it can connect builders utilities, obscure seams, joints and glue sealed components. Here, as a rule, used by professional glue gun with a special nozzle and thermostat.

Tool has become almost indispensable for designers, florists and lovers of such areas as "hand-made". With it, the production of various souvenirs, decorative items and handicrafts has become much easier.

Useful advice! Postcard made using techniques of drawing using polyurethane glue gun, will be an excellent and original gift. Particularly nice look beads and beads of colored or metallised droplets.

Hams, home craftsmen and designers, too, are not left unattended Engineering such a novelty, since the device allows even melt polyurethane. In this regard, the tool is a kind of decorative value, as artists can use it to create elegant frame structures in a grid, or is represented by a variety of hot melt gun subjects. This technique is often used for creating postcards, invitations and other holiday attributes.

Main advantages of the hot glue gun

Connection made with hot melt glue, leaves very reliable and is not inferior in strength characteristics fastening mechanically. Disconnect bonded parts is possible only by heating. At the same time on many surfaces after removing the adhesive is almost no trace, which is impossible in the case of drilling or nailing.

For example, the use of the gun is indispensable in the process of liquidation bespokrasochnoe dents on the car body. The technique involves gluing fungus (pistons) in a recess on the front surface of the extruded parts, then a special device, called minilifterom clinging to the cap and pull the dent formed on metal. After this fungus was removed by heating the surface.

Through the use of a hot gun can be ideal to fill voids, cracks and seal joints, soak the surface. In this case, the melt compared to other sealants, even in a large number of excellent and fully cures the entire depth for a minimum period - a maximum of 15 minutes. Although a small amount of glue solidifies, for 3 minutes.

Melt adhesive of not producing toxic substances, with regardless of the state - the cold or hot. The only risk - is the possibility of burns and damage to the materials which have higher heat-sensitive surface. The seam on the glued surface perfectly resists moisture. Rods for hot melt gun can be stored for a long time without losing its properties.

Thus, a secure tool, easy to use and quite ergonomic, so it can be used in children's crafts.

What can glue glue gun: interactive materials

With hotmelt gun almost instantly glued various components and objects. This is possible thanks to the fact that after heating the molten polymer solidifies just after 3 minutes. After curing, the seam becomes very strong, the need for a prolonged solidification, as is the case with the "liquid nails" or glue "Moment", is eliminated.

Important! Speaking about the advantages of glue gun, it should be noted its efficiency, as the price of hot glue, which is sold in the form of silicone rods, relatively low. It costs about two to three times cheaper than a reliable liquid glue of the same volume. At the same time, the adhesive mass can be dosed as precisely as possible, and the minimum amount of waste is obtained.

Glue for glue gun works seamlessly with a wide range of materials, which include a list:

• wood;
• plastic;
• PVC materials;
• glass items;
• leather;
• metal;
• ceramic parts;
• paper;
• rubber;
• textile.

I hotmelt inherent poor adhesion to certain minerals, such as concrete and plaster. Also, do not always like adhesive suitable for plastic parts. To get the maximum effect with the connection, the surface should be thoroughly cleaned of dirt, dust, oil stains, and dry thoroughly.

It should take into account the temperature factor - it is a kind of constraint, since it is not recommended to use a gun in the production of parts that are deformed under the influence of high temperatures. metal elements, on the contrary, it is necessary initially to heat, even using an ordinary hair dryer, because of the high thermal conductivity bases composition quickly cools and solidifies immediately.

The structure and material for the manufacture of hot melt gun

Melt outwardly looks like a hand tool, reminiscent of the famous eponymous weapon, which is not inserted into the cartridges, and a polyurethane core. During the warm-up glue turns into a fluid state. The most common diameter cylindrical rods cement gun - 7 mm, but there are thicker - up to 11 mm inclusive. Charging instrument from the back side.

The charge is inserted into the sleeve pusher extends further tubular receiver of rubber, then the rod It is driven into the chamber where it is heated and melted, transforming into the adhesive from penetrating ability. To start the heating is sufficient from 3 to 5 minutes. By pressing the trigger chute which acts as a piston pressure is created in the heating reservoir, whereby the nozzle at the bonding surface of the melt follows.

Melt housing made of rigid plastic material, which makes it possible to reduce heat transfer from the heating chamber and provide ease of product. Average tool weight is about 300 grams Quite often, the handle is provided with a special anti-slip vstavochki. It is hollow in the middle, there are placed wires is boring trigger. The main components of the tool are in the trunk.

On the Internet you can find a lot of video, how to use the glue gun, which, in addition to describing an operation contains detailed instructions on the structure of the unit and the location of its key details.

The operating principle of the heating unit, feed mechanism and coupling electrical glue gun

a heating chamber (heating unit) is disposed in the barrel, which is a metal tank. Beside it, usually below, the heating element is a so-called TAN. In certain models may be several heating chambers, which enables a more uniform and stepwise heating. Thus, the thermal unit is considered to be the main element, as is tool life depends on it.

Important! From the heating unit size and power performance depends PETN tool, which is manifested in the rate of melting and ready to use an amount of mass.

The feed mechanism - is an annular pusher. It can be further equipped with an engaging tooth, under the action of the lever runs, which merged with the trigger slide or rotary type. The design is quite capricious, so failure can not be excluded, especially if during the operation to try to get a large amount of glue. In most cases, the feed mechanism is matched exactly under a certain web resolution. Therefore, even slight variations in diameter can lead to malfunction.

Considering silicone gun device may be mentioned abutment guide sleeve is a tubular receiver which is located directly in front of the thermal camera. Its function - sealing "reverse", which prevents the penetration of the melt inside the gun. This detail - the weakest link, so as rubber aging and eventually bursts, and during overheating may miss material stopper with the moving parts. This results in damage to the wire insulation, can eventually cause a short circuit.

Features of the structure and functioning of the nozzle glue gun

The clutch can be damaged during attempts to scroll the charged core or remove it. In such cases it is better just to cut off part of the bar and skip the remains through the nozzle. This part, which is often called a nozzle or dyuzoy, designed to impart some form of adhesive mass, the dosing flow channel and overlap at the output. In dyuze also located off valve (also known as spring-loaded ball or pin) to prevent excessive leakage of melt.

Nipple not completely overlaps the nozzle in order to relieve excess pressure in case of overheating weight. Therefore, you must always lay a piece of cardboard under the spout. Direct-flow nozzles are also installed, but in this case the raw material is lost more.

Nozzles are made of metal coated with a top casing of rubber or silicone to prevent burns.

Many of the products are equipped with different shape and length of the nozzles. They are equipped with thread for connecting with the node heating and slots under the open-end wrench. It should be noted that to replace them is possible only in the heating condition, since all firmly fixed frozen adhesive solution.

An important detail body - this is a viewing window that allows you to control the size of the remaining rod or leaks from the couplings. Almost all products are equipped in the front of the case hinged stand. On the presence of the window often depends on the price of the glue-gun. The end of the handle for this purpose is equipped with special dimes. In between the work device is not suitable for laying on its side, since the shell in such position may overheat, and therefore will be subject to damage to the surface on which the tool.

Useful advice! Upon completion of the nozzle must be thoroughly cleaned of glue. To do this, hold them on a piece of cardboard several times.

Glue gun: how best to choose the technical characteristics

Power pistol hotmelt determined wattage heating assembly. The higher it is, the faster melt adhesive, although it is not important in terms of performance. In addition, it is necessary to take into account the capacity of the reservoir. If the heater provides the necessary temperature for operation and is required amount of glue in the chamber, the power is correct. Professional glue gun consumes 300 W and more, and for amateur enough power tool 30 to 150 watts.

There are manufacturers that offer products with autoregulation capacity. For example, for the heating power is needed 200 watts, enough for 40 watts in standby mode - up to 16 watts.

Features, requirements, advantages. Varieties of adhesive compositions and methods of their application characteristics.

The melting point of the hot melt adhesive is also important when choosing a gun. For the paper, textile items and certain polymers should be selected bars, which melt at a temperature of 105 ° C - it is under these conditions begin to melt almost all rods. At the same time, a major amount of guns can be heated to 170-200 ° C. Therefore, if there is no need for regular use of the gun, there is no sense to purchase an expensive copy. Optimal - unit is calculated on the melting point of the hot melt adhesive 160-170 ° C.

There is another concept, such as the speed gun, although more correct to speak about the performance, indicating the melt mass that comes out of the nozzle for a certain unit of time. Such information is contained in the passport of the product and may have an index of 5 to 30 grams per minute. For example, to work on a construction site will take a lot of glue, so it is best to take the rods with a diameter of 11 mm and a pistol - with high performance.

Choosing the glue gun on additional criteria

In deciding how best to choose the glue gun should be guided not only by its technical characteristics, but also to consider additional options that will greatly facilitate the work, making it much more comfortable and productive.

Pay attention to the temperature controller, which indicates the possibility of the use of tools for working with special materials, such as heat-sensitive. If more than three modes, this versatile tool.

If the gun is equipped with electronic temperature control in "automatic" mode, you should not be afraid of the unit overheating and significant loss of adhesive material. In this case, the tool itself changes the mode and with him to prilovchilis work. At the same time, a "smart" device itself off from the network, thus avoiding overheating, which significantly extends the life of the gun.

Useful advice! During the application of hotmelt gun safety rules must be followed when working with electricity and adhesive.

LED state of readiness in the form of LED tells that the device scored desired temperature and ready for use. In this case, there is no fear for the integrity of the mechanism, including receiving sleeve on the glue gun. Feedback from customers indicates that this feature is very useful.

The switch in the form of a button - an additional convenience, especially when having to disconnect power during continuous operation. This option is particularly relevant to devices not equipped with control electronics.

Are additional options needed in the glue gun: user reviews

There are many models that have, in addition to the listed set of basic and advanced options also a number of so-called "bells and whistles" that are needed in certain areas of work with the adhesive gun. In particular, the correct choice of the adhesive gun to some extent influenced by the presence and illumination of the working area, which is implemented with the integrated flashlight. This function is very necessary to work in hard to reach places.

On the exchangeable nozzle also should pay attention to. They are well extend the functionality of the appliance, as they give an opportunity to receive a different amount of adhesive mass, and oblong nozzles help to get into the blind area.

Nipple in the nozzle, used as an optional item, allows to largely reduce the amount of emitted glue pistol, In standby mode, and the viewing window helps to keep track of the size of the charged rod and monitor the integrity of the receiving clutch.

When choosing a gun with a leg-stand, should pay attention to its stability and practicality, which is manifested in the reliability of its fixing in the assembled state. Reliable and high-quality model glue guns have a pretty broad footprint including the claw on the handle, and sometimes trigger.

Actually, the trigger structure should also pay attention. The most convenient - is a mechanism with a rotary hammer, due to which a lot easier to keep track of the melt dosage without applying any extra efforts.

Ability detachably cord can significantly improve the ergonomics of the tool, as it allows to 20 minutes to work offline. Availability of additional options affect the price of Melt.

Features and Specifications rods glue gun

Glue sticks, also known as the spare tire and the stickers are different in diameter. The most popular option - a 7 and 11 mm. They are also classified according to shape, length, color and melting temperature. Before you decide which glue gun to choose, should determine the type of glue, which will have to work.

Useful advice! To work best to use a "native cores", which are supplied to the glue gun.

It should be noted that substantially all of the rods have a round shape, but constitute a separate category of guns, which operate on the oval reserve. As for the length of the rods, it may vary within the range 4-20 cm. It's worth noting that this criterion does not affect the final result, just in the process do not have to frequently change long stickers. The price of hot glue gun on this factor is also independent.

There are colored glue sticks, which are used to disguise the seams. The most common colors, besides the classic transparent, - a blue, yellow, red, white and black. In addition, manufacturers use color-coding to determine the destination of stickers, wherein transparent - it is universal, black - designed for sealing and yellow - for pasting products from glass.

Distinguished bars and melting temperature, although this factor does not affect the choice of the gun. Sticker low termopokazatelem simply will quickly melt away at the gun and is heated to 200 ° C. At the same time, high-rods which melt at a temperature of 150 ° C and above, are not suitable for pistols with slight heating. There are such expensive rods, respectively, above the price hotmelt gun.

The chemical composition of the adhesive for the pistol and its features

One of the major differences hotmelt besides color, size and a melting temperature, is its chemical composition. Half rods consist of thermoplastic polymers, the remaining proportion in the resin and plasticizers. It should be noted that the hot melt adhesive composition substantially harmless, because it does not contain harmful chemicals and organic solvents. The most common are based on a mixture of polyamide and ethylene vinyl acetate. glue gun for species composition:

1. Ethylene vinyl acetate (EVA-adhesives), the most popular, as are of good quality, and price for the glue gun is quite acceptable. Available in the form of rods, which can be glued any household products, used in the repair and even at a construction site.
2. Polyamide (PA-adhesive) used for gluing materials which require high strength and can resist the effects of both very low and high temperatures - from -35 to +135 ° C. A compound based on polyamides are not afraid of the impact of water, mineral and vegetable oils.
3. Polyolefin adhesives have high adhesion quality, so they are economical in expense, while possessing high flexibility as compared with other types of hot melt adhesives.
4. Polyester resin adhesives reliably glued parts of fiberglass, metal joining with glass, with a cork foil and asbestos with different metals.
5. Adhesives based on synthetic rubber after drying retain certain stickiness without losing the thermal stability. They have good elasticity and moisture resistance.
6. Amorphous polyalphaolefin (as a solid thermoplastic polyester) has good adhesion with regard to all surfaces except of Teflon. Especially it is used extensively in the automotive industry.
7. Reactive polyurethane adhesive composition after polymerization, forms a high-strength film, but the long solidifies.

How much is the glue gun: rating models

The assortment of pistols interlining very wide. After examining the above characteristics, we can only choose the appropriate model. The instrument itself has a simple design, so simple glue gun type the price is quite democratic - 7 to $ 10. For the money you can buy a functional device, but without additional options. If desired, and the presence of minimal engineering skills can build a glue gun with their hands.

Professional tool branded manufacturer is much more expensive - from 40 to $ 50, but it will open up its owner ample opportunities for bonding a variety of materials.

In manufacturing glue guns, many companies specialize. One of the most popular models - the glue gun "Bison 06850-60-12." It is a compact unit with a valve, which protects against leakage. For it suitable odinnadtsatimillimetrovye rods 30 cm long. Power consumption - 60W. Device equipped with a special valve, which prevents the falling drops to the workpiece, and the silicone lining protects the hand of the user from burns.

Quite a large difference in cost between the professional tools and glue guns for needlework. Price inexpensive device suitable for performing these tasks may start from 50 rubles. A striking example of this - the glue gun "Fixed Price".

It weighs less than 100 grams, being perhaps the smallest tool of this class. In the unit there are only 2-esteem - is the low price and compact size that is suitable for women and children. Deficiencies in this unit is much more basic ones - is the poor quality of components and short service life.

Thus, choosing a glue gun, should be guided by a variety of functional and technical control of the characteristics of the product, not just personal preferences. Also useful are reviews of consumers and professionals.
